How can I manually update my system after I postponed an update?

You can always check the software update status in your Hue app by selecting Settings > Software update. You can tap the orange “update” button when your software is out of date. Make sure to power on all of your lights that are marked for update. The orange “Update” button will not appear when the software is up-to-date. When your software is up to date, you do not have to do anything.
